Hello,

Regarding your issues:
1) refresh in background is not really possible right now, but once the dials are loaded they will stay there. If you have issues with that, feel free to contact me to my support e-mail. There are some known compatibility issues with Firefox and some cleaning and antivirus software.

2) click multiple times to open the dials page - this is the first time I hear this :) There is a good chance your Firefox needs reset:

3) you can increase Group list height in Options page to see all your tabs. You can also use "group-dials" to access your dials in the same way like files in folders - see my introduction video here:

I hope this helps :)

Have a nice day :)

Best regards,
